TRAVELER Filed Dec. 10, 1942 INVENTOR. PHILIP C. WENTWORTH ATTORNEYSPatented Nov. 9, 1943 UNITED STATES i" OFFICE 2 Claims.

In the spinning of yarns by the ring and traveler principle, thetraveler must necessarily respond to the many different strains from thebare bobbin to the full bobbin, no matter what style of building motionis used.

In recent years, many new developments have been introduced and added tothe spinning frame by machinery builders. Long draft spinning has becomealmost universal. This new development has affected the traveler ingreat measure because cotton yarn especially is now being spun from adifferent, character of roving. This rovin change has been brought aboutby reducing processes in the card room.

The introduction of long draft spinning was accompanied by the use oflarger rings and longer traverse. greatly increase traveler strains andaffect traveler performance materially in that in meeting these newspinning conditions, there is a greater tendency for the traveler toride the ring flange, due to the traveler swivelling on the ring. Ridingthe ring flange not only cuts into the traveler at a critical point, butit also gradually wears the ring flange itself and thus shortens thelife of both traveler and the ring.

With these considerations in mind, I have devised my present traveler.According to it, the horns of the traveler are split and spreadlaterally apart a distance sufiicient to stabilize the position of thetraveler on the ring, without increasing frictional contact. By givingthe traveler a relatively wide spread of bearing surface on the ring,the tendency of the traveler to swivel on the ring is greatly reduced.As a result, objectionable riding of the ring flange is proportionatelydiminished, and at the same time wear, due to frictional contact isreduced, and frictional heat is allayed.

In the accompanying drawing:

Fig. l is a perspective view of a traveler in accordance with myinvention.

Fig. 2 is a bottom plan view thereof, and

Fig. 3 is a diagrammatic indication of a ribbon of wire traveler stockin process of being progressively developed into spread horn travelersin accordance with my invention.

In the drawing I have indicated at H] the bow of my traveler, and at l lthe traveler horns generally.

Each horn is split centrally as indicated at l2, and spread laterally aslight distance to provide a pair of divergent balanced webs or tips l3.

Preferably each split I2 is in the form of a V, with the apices of the Vsplits terminating in the Larger rings and longer traverse relatedcurved portions l4 of the traveler which connect the traveler horns withthe bow.

The horns are spread a distance suificient to give the traveler a widerspread of bearing surface on the ring, thereby stabilizing its positionon the ring and reducing its tendency to swivel.

Actually such spread need only be relatively slight. In Fig. 2, thehorns are shown as spread but slightly beyond the bow, as indicated bythe dotted lines I5 in that figure.

In producing my travelers, I prefer to follow the procedurediagrammatically indicated in Fig. 3. In that figure I show a ribbon I6of traveler stock as having been longitudinally slotted at II atproperly spaced intervals corresponding to the location of the travelerhorns when the traveler blanks B are cut from said ribbon by makingsevering cuts l 8 centrally across the slots.

After the traveler blanks are severed'from the ribbon it, the half-slotsat each traveler horn are spread laterally by any suitable tool toproduce the spread horns. This is indicated by the dotted lines IS inFig. 3, Thereafter the blanks are bent to traveler shape over anysuitable anvil (not shown) and heat-hardened and polished.

Although I have shown the horns of my traveler as square-point indesign, it is obvious that their outer corners may be of rounded designif desired.

Similarly, if desired, the bow of my traveler may be slotted,perforated, or milled off at opposite edges.

These and all such other obvious modifications in structure, design, andmethod may obviously be resorted to within the spirit and scope of myinvention as defined by the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. A traveler to operate in substantially stabilized horizontal positionon a horizontal ring without substantial tendency to swivel and ride thering flange, said traveler comprising a bow and terminal horns, eachhorn being centrally, split to provide a pair of balanced ring-engagingportions, and each pair of ring-engaging portions being spread apart adistance sufiicient to provide a substantially wider spread of bearingsurface on the ring than would be afforded by the unspread horns of aconventional traveler of comparable size and weight.

2. The traveler of claim 1, the horns being split by V-cuts and theapices of said V-cuts extending substantially to the juncture of thehorns with the portions of the traveler which connect the horns to thebow.

PHILIP C. WENTWORTH.
